    Better than expected

    I expected a lower that had its upper removed for resale, but this was in a Colt bag with a part number indicating it was never marked with an upper. Fit and finish were impeccable, highly pleased with this purchase

    Best lower for us on the wrong side of the trigger

    Loving this M5 especially being left handed it just a smooth operating lower and rifle. Works great with every upper I’ve thrown on it including the Jakl.
